Abstract

The invention provides a throttling system capable of improving efficiency of a power grid. The throttling system comprises a first circuit, a second circuit and a third circuit, the second circuit and the third circuit are connected in parallel in the power grid, the third circuit is connected with a main circuit in series, and a throttling module is connected in series in the second circuit; thefirst circuit is connected with a singlechip and a first mutual inductor in series, the first mutual inductor is used for supplying power, a second mutual inductor in charge of monitoring current inreal time is also connected in the second circuit, the second mutual inductor is connected with the throttling module in series, the second mutual inductor is connected with the singlechip, and the singlechip is connected with an intelligent switch; and the third circuit is connected with a main switch in series. The system provided by the invention monitors and controls current in a power transmission line in real time by utilizing the throttling module arranged on the power transmission line and cooperating with the second mutual inductor and performs intelligent selection on functions of the throttling module by utilizing the singlechip to receive a signal transmitted by the second mutual inductor, so that timely automatic throttling power supplying performed when a power supply line isin an overload state and even short circuit is realized, power consumption is prevented, and power utilization security of a user is also improved.

Description

technical field [0001] The invention relates to the technical field of power grid systems, in particular to a throttling system and a throttling method for improving grid performance. Background technique [0002] The whole composed of substations of various voltages and transmission and distribution lines in the power system is called the power network, or power grid for short. It includes three units of power transformation, power transmission and power distribution. The task of the power grid is to transmit and distribute electrical energy and to change the voltage. [0003] In recent years, with the continuous acceleration of China's electric power development, China's power grid has also developed rapidly. The operating voltage level of the power grid system has continued to increase, and the network scale has also continued to expand. Power grid and China Southern Power Grid have 6 large-scale regional power grids across provinces, and have basically formed a complet...

Problems solved by technology

[0004] However, the current power grid generally has problems of high power consumption and low safety during power transmission and distribution, especially for some large-scale electrical equipment and enterprises. The excess power supply, the current in the transmission line exceeds its rated current, causing the power grid to heat up, or even burning the cable to form a short circuit, resulting in a large amount of waste of electric energy, which is not conducive to improving the efficiency of the power grid

[0005] Some users will add protectors at the access end of the power grid, such as air protectors, fuses, etc., but these protectors will directly cut off the power in the event of a short circuit, and the office staff will easily lose data or data in order to save, which brings great harm to users. big trouble
